In all those years what have you determined?
That you couldn’t reconcile the scriptures with known history.
Myth may as well be synonymous with fiction. You should use the word fiction if that is what you have concluded.
That neither books about Abraham, Joseph & Moses could name any of the kings that they were supposedly “contemporary“ to, because i think the authors (of Genesis & Exodus) didn’t write during those times (eg Bronze Age).
Take for instance, Joseph in Egypt, the authors have named the Joseph’s slave master - the king’s guard captain, Potiphar (Genesis 39), and have named Joseph’s father-in-law, the high priest of On (Heliopolis) Potipherah (Genesis 41), two insignificant fictional characters, BUT couldn’t name the king of Egypt, who made Joseph the second most powerful person in charge of Egypt, other than calling him “pharaoh“, which isn’t a name but title for a monarch that wasn’t even used in Egypt until the 18th dynasty, eg from 15th century BCE and onwards.
Then in the Exodus, like Exodus 1 & 2, the king who ruled Egypt at the time of Moses’ birth, not only the king was nameless, so was princess - the King’s Daughter (Exodus 2) - just as nameless and yet she had adopted the foundling and raised him in the “royal” family.
And it is most likely a different king was ruling Egypt, 80 years later, who eventually allowed Israelites, their freedom, after Egypt been through a series of plagues, but this king was also nameless.
My guess, is that the authors of Genesis & Exodus were living in Babylon at the time of exile (6th century BCE), have no access to Egyptian sources or records, so they invented stories where the kings (and 1 princess) weren’t given any names that could have identified which the Bronze Age dynasties & periods.
Without any names of Egypt’s monarchs, people have to guess when the stories of Joseph and Moses as to what periods they were contemporary.
Plus, there are no Egyptian records that can verify the events claimed in Genesis & in Exodus.
Dis you know many of Egypt’s monarchs, not only the names they were born with, but their royal names (written in hieroglyphs and within cartouches) too, their names also appeared in king lists or in royal annals.
Plus we know of their names of their fathers, mothers, husbands, wives, sons, daughters, etc? As a king often married his sister(s), incest was normal practice.
These names are often found inscribed on stone walls of tombs, or on sarcophagus or coffins, or inscribed on stone stelae that recorded their achievements. These are what I would call “CONTEMPORARY” RECORDS.
That’s one of the main reasons why I view all stories prior to the kingdoms of Judah and Israel, to be mythological, as none of it can be verified, historically or archaeologically.
